The Bolivian warbling finch is a species of bird in the family Thraupidae. It is found in Argentina and Bolivia. Its natural habitat is subtropical or tropical high-altitude shrubland.
Region
Andes Mountains
Typical Environment
Occurs in the inter-Andean valleys and montane slopes of southern Bolivia and northwestern Argentina. Prefers subtropical and tropical high-altitude shrublands, arid scrub, and brushy slopes with scattered bushes. Frequently uses edge habitats, such as hedgerows, fallow fields, and the margins of open woodlands. Often found in areas with rocky ground and patchy vegetation where it can forage both on the ground and within low shrubs.
Altitude Range
1800–3800 m

A high-Andean tanager, the Bolivian warbling finch was long placed in the finch-like genus Poospiza but is now commonly treated in Microspingus after genetic studies. It often forages low in shrubs or on the ground and may join small mixed-species flocks. Pairs maintain small territories during breeding and give a sweet, musical warble from exposed perches.
Temperament
social and active
Flight Pattern
short rapid wingbeats
Social Behavior
Typically seen in pairs or small family groups, sometimes joining mixed-species flocks while foraging. Nests are placed low in dense shrubs, with both parents involved in provisioning. Territorial behavior increases during the breeding season, but birds remain loosely gregarious at other times.
Migratory Pattern
Resident
Song Description
A clear, sweet warble made up of short phrases of whistles and trills. Males often sing from the top of shrubs or small trees, with soft contact calls used while foraging.
Plumage
Mostly grayish-brown upperparts with paler, buffy to whitish underparts and subtle rufous tones on wings and flanks; neat, fine facial patterning with a pale eyebrow and contrasting lores. Tail and wings show darker feathers edged with warm rufous. Overall appearance is clean and soft-toned, suited to shrubby, arid slopes.
Diet
Consumes small seeds, grass seeds, berries, and a variety of arthropods such as beetles and caterpillars. Seeds are taken both from the ground and directly from seeding heads. During the breeding season, insects form a larger part of the diet to provide protein for nestlings. Will opportunistically take small fruits when available.
Preferred Environment
Feeds in low shrubs, along scrubby field margins, and on open, rocky ground with scattered vegetation. Often works methodically through bushes and along the ground in pairs or small groups.
